SN74LVC16543DGGR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVC16543DGGR is a 16-bit registered transceiver with 3-state outputs manufactured by Texas Instruments. It operates at a supply voltage (VCC) of 2.7 V to 3.6 V and supports an operating temperature range from -40°C to 85°C. The device features independent latch-enable, output-enable, and direction-control inputs for each 8-bit section. Propagation delay ranges from 1.5 ns to 9 ns depending on the control signal and voltage. Output drive capability reaches ±24 mA at 3 V. The component utilizes EPIC submicron CMOS technology and includes active bus-hold circuitry on data inputs.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Features active bus-hold circuitry on data inputs to maintain valid logic levels without external pullup or pulldown resistors.
• Provides independent control over data flow direction and storage mode via separate latch-enable and output-enable inputs for each register section.
• Designed for low-voltage operation using Enhanced-Performance Implanted CMOS (EPIC) submicron process technology.
• Latch-up performance exceeds 250 mA per JEDEC standard JESD-17 specifications.

Buffers, Drivers, Receivers, Transceivers Applications

• Low-voltage memory mapping applications
• Clock-driven bidirectional data buses
• Bus-oriented architectures requiring registered transceivers

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DGGR' corresponds to the Thin Shrink Small-Outline package configuration. Confirm that the revision level matches the latest SCAS317A datasheet to ensure parameter accuracy. Check for RoHS compliance status as manufacturing processes may evolve. Ensure design-in documentation references the correct absolute maximum ratings to prevent damage during power-up sequences.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring 16-bit wide data transfer with latching capabilities at 3.3 V logic levels. It serves as a suitable alternative to older ABT series devices where lower voltage operation is required. Consider the package size constraints and thermal dissipation requirements associated with the DGG package. Verify input voltage compatibility with the source logic family to ensure proper signal integrity across the recommended operating conditions.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the Widebus Family of Texas Instruments logic products. It is part of the LVC series, designed specifically for low-voltage applications. The SN74LVC16543 functions similarly to other 16-bit registered transceivers but distinguishes itself through its specific EPIC process technology and integrated bus-hold features. It is distinct from non-registered variants like the SN74LVC16542.
